Duplicate product error (SOLVED)

I had to do a reinstall of Joomla 2.5. I backed up the DB's prior to the reinstall. When I restored the backup I can see all the products that were in the DB originally. The problem is that I can not modify, or add products. I also noticed that all the images are not displaying. When I attempt to save a product without any modifications or edits I get this error. A product with the same code already exists Error Saving. I can not find any duplicates and viewing the databases does not indicate there are duplicates. My hosting company has done a server restore for me but problem still exist
Any help would be appreciated. Thanks, Charles
I removed Hikashop and reinstalled it hoping my products would remain intact. They did and I just need to make some minor modifications
